Abstract (en)
[origin: EP0829781A1] For efficient operation of a thermoelectrically operated timepiece, heat is transferred into and out of a thermoelectric device by mounting a thermally conductive plate (4) on the thermal energy output side (3b) of the thermoelectric device and placing the plate in direct contact with a heat-dissipating frame (5) made of a material having a high thermal conductivity. The heat-dissipating frame is placed on the top surface of a case body (9). The thermally conductive plate uses a material having a high thermal conductivity. As a result, the efficiency of the thermoelectric conversion can be improved. Also, heat can be dissipated efficiently. <IMAGE>
